GOMF SINED MILKING AND SEPARATING MACHINE AND OPERATING MEANS THEREFOR.

Specification of Letters Patent. Patented FBILZG, 1917.

Application filed April 2, 1913. Serial No. 758,427.

To all whom it may concern:

'Be it known that I, Penna JENSEN Pmnrs- HVARRE, a subject off-the Kingof Denmark, and a resident of Copenhagen, in the Kingdom of'Denm-ark,have invented a new and useful Combined Milking and Separating Machineand Operating Means Therefor, of

which the fol-lowing is a description.

My invention relates to the class of milk ingand separating machinesused in theproduction-of milk and cream for dairy purposes, the nfilkingmachmes belng used for the withdrawal or milk from cows and 'theseparating machines being used for the sepa-i ration of, the milk intocream and skim milk, and the object of my invention is taproduceacombination of these machines by which milk may be withdrawn from thecows, separated into cream and skim milk and canned or otherwise madeuse of without exposure to the open air and in one can present inventioncontemplates a suitablejjmilking apparatus comprlsing one or more setsof teat cups with the necessary mechanical actuating means operated by.electrlc,

hydraulic or pneumatic power combined with a centrifugal separator insuch a mannor that the several teat cups, together with their connectingmilk tubes, serve as the hopper o as hopper feeders to the centrifugaldriilii in which the separation *takes placefthe whole mechanism beingcombined in one portable device adapted for personal application to thecow with the aid of suitable supporting frame, bracket or belts. v

The teat cups may be of any suitable type that is operated by compressedair or other.

fluid and which delivers the milk to piping and the centrifiigalseparator may be of any type of a movement size embodying a'rotatingbowl and liner within a suitable casing provided with milk inlet orinlets and with cream and skim milk outlets, my invention hay-mgprincipally to do with the means which. being supplied with compressedair or other fluid from a suitable pump, causes the teat cups andseparator to work in harmony. a

In the accompanying drawings- Figure 1- illustrates one form of myinvention embodied in an-outfit comprising .teat cups, controllingmeans, separator, air

supply pipe and supporting bracket for. use with onecow.

Figs. 2 and 2 .are details of a pulsator casing and valve. v Fig. I 3 isan enlarged vertical section through the operating means and. separator.

Fig. a is a modification, in which an electrio operating means andseparatoris used,

. feeding directly into cream and skim milk cans, the construction beingapplicable to two cows as illustrated. 1,

11 1s a cushioned yoke adapted to rest upon the back of a cow andsupporting,

through bent arm .12, downward extensions 13, attaching bracket 14., andair supply pipe 17,-and separator 18. 'Compre'ssed air or other fluid issupplied to the. operating means 17, through pipe fitting 15, bypiping19, from a suitable pump not shown.

The teat cups 16 are preferably ofa form fitting 15, the teat cups 16,operating means illustrated and claimed in a copending application filedof even dateqherewith, each teat cup being operated by compressed airthrough three or more smallrflexible pipes 20, 21"and 22, and.delivering milk through pipe 23. i

The centrifugal separator comprises the usual rotating bowls 24 and 25,mountedon a shaft 26 having its ends bearing respec-' tively infoot-bearing- 27, in the bottom part 28 of a two-part casing, and in asteadybearing 29 in the top part 30 of a tworpart casing. The bottompart. 28 is provided with a skim milk outlet 31 and the top part 30 isprovided with a cream outlet 32 and a number of milkinlets. 33 feedingto an. axial chamber 34 above the separator bowls,

to the top part 30.

. On top of-the toppart 30 of the casing is mounted and removablysecured the opcrating means comprising ,a disk-shaped member 35 havingan airinlet 36 leading to an axial chamber 37,5111 air outlet 38 leadingto an upwardly extendingpassage in a tube driving gear or air motor; anair' motor comprlsmg a turbine wheel 41, gear wheel 42, intermediategear wheel 43 mounted on .39, and anaxial outlet 10 leading-to the ,Vthe bottom part 28 being removably secured a stub shaft 44, large gearwheel 45 and ripheral rack 48 a bell-shaped inner shell 49, a seconddisk-shapedmember 50 resting on the disk-shaped member 35 and in whi hthe air motor is mounted; an outer shell 51 inclosing the inner shell49; a top member or hood integral with outer shell '51 and littingontube 39, and containing an axial chamber connecting through horizontalair inlet passage 74 with the passage in the tube 3!.) in one directionand with air outlet holes 56. 57. and 58, 59, 60, ex-

tending through the wings 6i and 62 resp'e(':tively, the'entrances tothe air outlet holes "being controlled by the rotating valve or pulsator63 formed in the top ,of the shell 49 beneath the axial chaniber53, in

the other direction; the turbine wheel 41 being; secured on a verticalshaft 64 having its upper cndin an adjustable bearing 65 inthe top ofthe hood 52, the shaft passing through the valve, orvpulsator 63., thedisk shaped member 50, and the gear wheels-2, secured to shaft 64whichis provided with a clutch connection 86 for driving the shaft 26.

Theinner shell 49 has a series of air outletports 66 allowing the airwhiclrpasses through and operates the turbine wheel 41 to escape throughports 67 in the outer shell 51, and the valve or pulsator 63. formed ini the top ofthe inner shell 49 has an inner cavity'or circular port asit were 68 com- 57, 58,59, and 60 and is further provided municatingwith'the air outlet holes 55, 56

with an outer recess 69 allowing the air outlet holes 55, 56, 57, 58,59, and .60 in the hood 52 to communicate with the exhaust 'ports' 70 inthe outershell. The ports are arranged n groups and series according tothe pulsation desired in theteat cups. The

arrangement for a four teat cup operation fbeing shownjin Figs. 2 and:2. '45

;pressed air from the pum enters throu h A, inlet,36-to'the ax1al ch'amer 3] where the In the operation of the device the coin current divides,one part of the air passing upwardfthrough the outlet tothe turbinewheel 41 and out through the ports 66 and 67 to vthe atmosphere, theother part of the airpassingthrough outlet .38, tube 3.9, horizontalpassage 54, and to chamber 53,

' wherethe air is furtherdivided, the several currents passing out orpulsating 4 through the various holes. 55, 56, 57, 58, 59,

. ports ofthe-outer shell as the valve or pulsator rotates.

'In Fig. 4 I have shown an embodiment of the invention in which themotor is designed to be operated by an electric current. the

construction illustrated being applicable to two cows, although bysuitable connection a more or less number may be operated on. Theseparator 71 is driven by suitable gear- 1 ing from the motor 72, andthe pressure form the teat cups is furnished by a pump 73 on the sameshaft as the motor. The milk is received by the separator 71 from theteat cups 16 through pipes 74, connections 75 and piping 76, the creambeing discharged from the separator 71 directly into the smallreceptacle 77, and the skimmilk being discharged through pipes 78 intothe larger receptacle 79. The electric supply may come from any suitablesource through the con- .nection 80 and conductor 81.

Having thus described my invention the following is what I claim as newtherein and desire to secure by Letters Patentz l. The combination, witha milking ma- 5 chine; of a separating machine and means whereby themilking machine and separating machine may be suspended from the body ofthe animaloperated on.
